With the support of the National Cancer Institute, the Given Institute of Pathobiology has established itself as a center for disseminating the latest advances in cancer research not only to basic science and clinical faculty members, but also to graduate and medical students, residents and postdoctoral fellows. Our objective is to report current knowledge and generate and exchange new ideas concerning carcinogenesis, including viral, immunological, physical, chemical and hormonal factors, and to correlate the newest biomedical knowledge on carcinogenesis with diagnosis and therapy. It is our intent to provide a series of interrelated seminars and workshops aimed at concepts, problems, and accompanying techniques.
